EPECIPICATION forming part of Letters Patent No. 322,552, dated July 21, 1885.

Application filed May 29, 1884. (No model.) 7

printing devices being arranged at each end of the machine and adapted, by means of suit; able guide-rollers,to receive,print, and deliver the web therefrom at a point about the center of the machine into and between the feeding and severing rollers, and from thence through the folding-rollers.

The construction and operation of the machine will be hereinafter described, and the novel features thereof will be specifically set forth in the claims.

Referring to the drawings, Figure lis aplan. Figs. 2 and 3 are side elevations; Fig. 4:, a central vertical section. Fig. 45" is a plan of the receiving-box and the packer-operating arm; Figs. 5 and 6, end elevations; and Figs. 7 and 8 are details, hereinafter described, of a printing anwil gal ll hineconstructed in accofilancewith my invention. Figs. 9 and 10 are diagrams of opposite sides of a severed portion of a web,showing the fold-lines therein as formed by the folding mechanism.

Like letters and figures indicate like parts in all the drawings.

The moving parts of the machine may be supported in any suitable frame-work; but in this instance Ihave constructed and illustrated acompound framework-that is to say, the frame comprises two sections, 1 and 2, the former adapted to support the printing mechanism and the latter the folding mechanism, and each connected to the other in such a manner as to be separable therefrom bodily, and yet so that the frame-work supporting the folding mechanism is capable of receiving the product of the printing mechanism. An advantage of this construction-separable frames-is that access to the folding mechanism may be had for repairing or other purposes.

The frame-work of the printing mechanism rests directlyupon that of the folding mechanism, and is secured in position by bolts 3, and along the line dividing the two sections are formed at proper places bearings for certain journals or shafts hereinafter described, which shafts, in connection with suitable tiebars or cross-beams, serve the purpose of strengthening the frame laterally. Examples of such tie-rods are illustrated at 4 in thelower portion of the frame-work.

Section 1 of the framework comprises two bars or standards, 5, for impression-cylinder 6,and standards 7 forthe ink-distributing rolls 8. It is also provided with standards 9 for the web guide rollslO, and adjustable brackets 11, provided with bearings for a pressure feed-roll 12, said brackets being pivoted to the cross-bar 13, (extending from the standard 9 to thestandard 9,) and maintained in position to cause the roll 12 to bear with greater or less force on the roll 10 by means of the bolt or screw 14, set in the bar 13 and passing through a slot, 15, in the bracket. The bar 13 is extended to serve as a support to the ink-we1l 16, which is of the usual construction, and caused to feed by means of the pawl 17, pivoted to the arm 18, mounted loosely upon the shaft of the ink well roll, which carries a ratchet, '19, said arm being operated through the medium of the connecting-link 20, pivotally secured to the arm and to a lever, 21, pivotally connected to the arm 22, pivoted to the frame-work over the cam 23, mounted upon one of the transverse shafts therein.

The type-beds 24 are of that class which are provided with racks 25 and lugs 26, (see dotted lines, Fig h) and which are thus adapted to be operated by means of pinions 27 mounted on shafts 28, one of which shafts is directly connected with the impression-cylinder gear '29 by means of the pinion 30, (see Fig. 3,)

the other pinion and shaft 28 being driven by an intermediate pinion, 31, mounted on an in termediate shaft, 32, the lugs 26 riding inways 33, formed in the inner surfaces of the side pieces of theframework. Cushioning-springs 123 are arranged at the outer ends of the ways and overcome the momentum of the forms as they change direction at that point in their travel.

It will be readily understood that the typebeds 24 are successively brought beneath the impression-cylinder 6, so as to print both sides of the web, passing over the guide-rolls to one of the impression-cylinders, from thence to the other, and, finally, between the rolls 10 and 12, near the folding mechanism, which will be hereinafter described.

Such features of construction as have been thus far herein described, and which are of my invention and not claimed herein, are left unclaimed by reason of their being claimed in the above-named application.

A, Fig. 4, represents the web in its passage through the machine as far as can be illustrated without detriment to the clear illustration of the parts thereof. The direction ofthe movable parts of the machine is indicated by arrows as fully as is necessary to a clear understanding of the operation of the machine.

Any of the shafts of the machine may be selected as the power-shaftfor example, one of the shafts 28and the two shafts 28 are connected to each other by gears 34, (see Fig. 1,) and each of the shafts is provided with a cam, 35, in which the pin 36 rides, said pin projecting from a lever, 37, pivoted at one end to the frame-work and pivotally connected at the other withone of the ink-distributing rolls 8, by which means said roll is given a longitudinal reciprocation, as is usual in inking mechanism. The cam 23 is mounted upon one end of one of the bed-operating shafts 28, and once during each revolution lifts the arm 22, and this operates the arm 21 and link 20, by which means the pawl 17 is operated and a transfer-roll, 38, is carried back and forth from the ink-well roll to one of the ink-distributin rolls 8.

The pinion 30 upon shaft 28 meshes with a geared cam, 39, having a single operatingpoint, 40, (or curvature in its track) which, in connection with suitable levers, rock-arms, and connecting-rods of a certain relative length, location, and proportion, serve to operate all the moving parts of the folding mechanism, the whole of which is timed with due regard to the delivery of the printed web from the superimposed printing mechanism.

As the web passes from between the rolls and l1,it is guided by an apron, 41, mountd upon a tie-rod, 4. into the bite of the sevring and feeding rolls 42, provided with persorating-blades 43 and 44 and with spring ngers 45. By reference to Figs. 7 and 8 the onstruction of the perforating and severing lades will be readily understood. In theroll i aving the'spring-fingers there are two plates .ior plain blades,44, separated from each other so as to receive the single perforating-blade 48, mounted in the opposite roll upon pins 46, passing through inclined slots 47 in the boxing 51 of the perforating-blade. The blade 43, when otherwise not affected, projects from its roll sufliciently to simply perforate the web as it passes through the rolls-for instance, on the line 1, Fig. 9. At the completion of every other revolution of the rolls a lever, '48, having a projection, 49, is thrown into the path of the projecting end of the perforatingblade 43, which is normally held retracted by a spring, 50, secured to the end of the roll 42. Said spring bears against the end of the perforatingblade, so as to normally hold the same partly within the roll; but the said spring also yields when the projection 49 comes in contact with the opposite end of the perforating-blades, and it is forced longitudinally and outwardly, the latter course being taken by reason of the inclination of the slots 47, so that at the completion of every other rotation ofthe rolls the said perforatingblade is thrown outwardly from its roll between the two plates 44 inthe opposite roll such a dis tance that it not only perforates, but is intended to completely sever the web at every second revolution of the rollsas for instance, on the line a, Figs. 9 and 10so that the web in passing from a to a, between the rolls 42, is perforated on the line 1 and severed at the line a.

In the modified form of perforating-blade shown in Fig. 8, instead of arranging the spring 50 at the end of the roll I secure it to the boxing 51 of the perforating-blade, and instead of arranging the slots 47 in said boxing they are formed in the blade.43 itself. Either of these constructions may be employed, as desired, and in both constructionsthe boxing is firmly seated in the roll which carries the perforating-blade.

In Fig. 4 the lever 48 is shown by heavy dotted lines as projecting into the path of the blade 43 and in light dotted lines as out of the path of said blade. The said lever is pivoted at 51 on the inside of the frame, and is pivotally connected to the connecting-rod 52, pivotally attached to a rock-arm, 53, rigidly mounted on the shaft 54, passing through said side frame, on the outer end of which shaft is another rock-arm, 55, provided with pin and friction-roll projecting into the'cam 39, so that during each revolution of the cam the rock-arms are oscillated and the lever 48 is thrown into the path of the perforating-blade.

The gear 56, mounted on the shaft of one of the rolls 42, is one-half the diameter of camgear 39. The said rolls being geared together, they must make. two revolutions to one of the cam gear, whereby the perforating-blade is transformed in function to a severing-blade once during every second revolution of the rolls 42.

The rolls 57 are ordinary folding-rolls, with the exception that'the upper one is provided with a plain bar or blade,58, which (by means of a lever, 59, thrown into and out of the path of a projecting end of said bar) is projected from the roll while blade 43 is against it to assure'a complete severance of the web along the line a after the perforating function of the blade 43 has been performed. Lever 59 operates withblade or bar 58 just as lever 48 operates blade 43. The contact of blades or plates 58 and 43 with each other is intended IFO IIO

to accomplish a positive separation of the web along the previously-perforated line by reason of a slight movement of the one upon the other, which is in the nature of a rubbing action. Now, the rolls 57 being one-half the diameter of the rolls 42; and geared together by the pinions 60, mounted on their shafts, the upper. one of such pinions meshing directly with the gear 56, and thus indirectly with the cam-gear 39, and being one-fourth the diameter ofsaid cam-gear, an operation of the lever 59 (through the medium of the connecting-rod 61, and rock-arm 62, mounted on the shaft 63, having the outside rock-arm 64,provided with a pin projecting to the cam-groove of gear 39,) must follow at each passage of the point 40 of the gear and the lever 59 will be thrown into the path of the bar 58 and, by reason of the proportion existing in the rolls 57 and their companions relative to the diameter of the canrgear, said lever 59 will be operated once in every fourth revolution of said rolls 57, and these rolls are so timed with relation to rolls 42 that the said bar 58 willbe thrown directly alongside of perforating-blade 43, which projects slightly from roll 42, so as to assure the separation of the web,as before described. V

A rotary brush,65, runs in contact with one of the rolls 42 and in a direction opposite to its rotation, to insure the deliverance or direction of the leading endvof the web downwardly in front of the rolls 57. The brush is rotated by means of a gear, 66, which meshes with severing-roll gear 67, as clearly shown in Fig. 2, there being an intermediate gear,68,to give the brush the right direction of rotation.

The leading end of the web is carrieddown in front of and below the rolls 57 to such a distance as is necessary to bring the line 1, Fig. 9, opposite the bite-line of said rolls,when the first fold is made along said line 1, which has been perforated as before described. The means for making the folds upon the line 1 is an oscillating folding-blade pivoted on a shaft, 70, operated by means of a rock-arm, 71, (see Fig.3,) aconnecting-rod,72,and arock-arm,7 3, loosely pivoted on a shaft, 54. Between the pivotal joint and rock-arm 73 there is pivotally connected with said rock-arm another link,7 5, which carries a pin and friction-roller 76, which projects into the groove of the cam. To said pin are connected also a suspension link, 77, pivotally secured at 78 to the framework, and a connecting-rod, 79, which is pivotally connected to arock-arm, 80, rigidly secured to an upright shaft, 81, on which is mounted the rock-arms, 82, which carries the final folding-blade 83, hereinafter referred to. The suspension-link serves the purpose of retaining the pin 7 6 against downward movement when it is forced in lateral directions by the point- 40 of the cam; and by this combination and arrangement of connecting rods, rock-arms, and suspension link several independent devices in the folding mechanism are in proper relative time operated by the singlepointed cam.

The folding blade 69 is provided with spring-fingers 84, depending therefrom and arranged to depress the web against a raised portion of a curved plate or bed, 85, and

while so held by the fingers the web is touched by -a paste-dabber, 86, (which is a piece of leather, rubber, or other suitable, material,) held between clamps 87, and extending a distance equal to or slightly greater than the width of the web,and mounted in rock-arms 88, mounted on a shaft, 74, and connected by a link, 89, to the arms of the folding-blade. To said arms is secured a second link, 90, which is pivot-ally connected to an ordinary pawl and ratchet for operating a paste-roll, 91, running in a pastevat, 92, so arranged that in its oscillatory movement the paste-dabber 86 shall come in contact with the paste-roll 91 and carry paste therefrom to the web when it is held against the-bed 85, as described.

The relative proportion in size of the' feeding and severing rolls 42 with the cam-gear 39 is such that the folding-blade 69 and the paste-dabber 86. are operated once and substantially simultaneously during every two revolutions of said rolls, so that a single line of paste (on theline 2 of Fig. 9) is applied upon each severed portion of the web, so that when thefold is made on the perforated line 1 and the two portions of the web at each side of said fold-line are brought together in passing through the rolls 57, the said port-ions of the web are caused to adhere to each other along the said line 2.

As the now-folded web passes through the rolls 57 ,it is delivered upon a table or bed, 93, having a transverse opening over the second folding-rolls, 94. An oscillating folding-blade, 95, operates in connection therewith to form a second transverse fold on the lines 2, Fig. 9. At this point the severed portion-of the web is folded into an eight-page paper, being secured by paste along one fold-line, and being perforated along the other foldline, whereby it is susceptible of severance along said first fold-line to gain access tothe second and third pages thereof.

- The foldingblade 95 is mounted upon a shaft, 96, having a rock-arm, '97, on the outside of the frame, and having connecting-rod 98 pivotally connected with a rock-arm, 99, mounted on the shaft 100, suitably supported in the framework and having at its free end pin 101, projecting into the groove of cam 39. The folding-rolls 94 are operated by means of gears 102, meshing with an intermediate, 103, which meshes with the gears of folding-rolls 57.

Now, in order to double the number of pages in the severed portion of the web, a vertical pair of folding-rolls are arranged beneath the folding-rolls 94, so that the previously-folded sheet is delivered in front of,andis passed between the same by the heretofore-mentioned IOC IIO

folding-blade 83, the dotted line at A, Fig. 4, indicating the folded paper passing with the blade into the bite of the rolls. In making this fold in the previously-folded sheet the paster 86 should be thrown out of action by disconnecting its link 89 from the foldingblade 69, and any suitable well-known pasteapplying devices, 69%, may be arranged to lay a line of paste along the fold-line 3 of Fig. 9, one of the rolls 42 being grooved circumferentially at 42%- to avoid contact with the said paste-line in order to bring the pasted portion of the web on the final fold-line. The foldingblade 83 folds the severed portion of the web along the line 3. Paster .86 should be thrown out of action when paster 69'}- is in use.

Now, it will be noticed by reference to Figs. 9 and 10 that when the last fold is made a sixteen-page paper is formed by each of the severed portions of the web produced in the manner described, the numbers at the corners of the divisions made by the folding lines of said portions, as illustrated in Fig. 9, being the page-numbers as they occur in the completelyfolded portion on one side of the web, and the similarly-arranged numbers in Fig. 10 indicating the pages produced by the printing upon the opposite side of the web and the subsequent folding thereof, as described.

The vertical folding-rolls 104 are operated by means of pinions 105, arranged at their lower ends; and the miter-gear 106, arranged at the lower end of one of the rolls, meshes with another miter-gear (not shown) on the horizontal shaft 107, (see Fig. 2,) carrying a miter-gear, 108, meshing with a companion, 109, mounted on a vertical shaft, 110, arranged outside of the frame and carrying a mitergear, 111, meshing with a companion, 112, mounted on one of the horizontal folding-rolls 94. 113 represents a receiving-box having a packer, 114, reciprocated therein by means of a bell-crank lever, 115, secured to a vertical shaft, 116,0perated by means of a connectingrod, 117, and a second bell-crank lever, 118, pivoted to the framework and carrying a pin, 119, projecting into the groove of the cam 39. A spring, 120, (see Figs. 2 and 4,)secured to a side wall of the receiving-box,projectsinto the box and into the path of the packer 114, so that as the packer, when reciprocated to compress the papers within the receiver, reaches a point beyond the free end of the spring, (shown in elevation in Fig. 2, and in section in Fig. 4) said spring is compressed against the side wall and remains there until the return of the packer, when it immediately springs outwardly and retains the papers from following the packer in its backward movement. In front of the packer is a spring-seated follower or plate, 121, extending along the side of the box 113, and bent at a right angle to extend less than the entire width of the receiving-box, as clearly shown in elevation in Fig. 2 and in section in Fig. 4. The coiled spring 122 is housed in the recess formed at the side of the receiving-box,

and secured at one end to'a portion of the retaining-plate 121, and at the other end to a wall of the recess, so that when it is desired to remove papers from the receiving-box the said plate may be drawn toward the side of the machine and against the tension of the spring withone hand, while the papers are removed from the box with the other.

Instead of dividing the two sections of the frame along a line which necessitates the forming of half-boxes in each section for the shafts 27 and 28, the upper section may be depressed, as shown in Fig. 2, at the line 124, where said shafts pass through,'so that whole bearings for said shafts shall be in the upper section. Various other changes in theoutline of the joining portions of the two frames may be made, and yet secure the advantage of bodily separation of the printing mechanism from the folding mechanism.

By using properly-proportioned gearing, the rolls 57 may be onethird the diameter of rolls 42, and other changes in proportion of the rolls and cam-gear, arms and levers may be made, if desired; and, furthermore, asingle set of printing devices may be employed with the folding devices, or the printing and folding mechanism may be used separately.

A companion application, No. 133,592,discloses some of the features herein shown and described and not claimed, and having particular relation to a modified construction of the frame-work and means for moving the beds therein, and other features hereinshown and not claimed are shown in my patent No. 305,469, having reference to the same devices and mechanism for operating them in connection with the impression-cylinder.
